In Trichomonas vaginalis, a TvCyP1 cyclophilin was previously demonstrated to regulate the nuclear translocation of Myb1 and Myb3, which respectively repress and activate transcription of an adhesion protein ap65‐1 gene. In the present study, TvCyP1 was found to bind to Myb3 at sites spanning 54Gly‐Pro55 and 72Gly‐Pro73 with differential affinities. When Gly54 and Gly72 in Myb3 were both mutated,...
A type III Trichomonas vaginalis virus, which may be involved in transcriptional regulation of the major surface protein gene P270 of the protozoan pathogen Trichomonas vaginalis, was purified and characterized in the present study. The complete 4844-base-pair complementary DNA sequence of the viral genome reveals overlapping cap and pol genes with a putative ribosomal frame-shifting signal within...
Trichomonas vaginalis viruses (TVV), which may regulate P270 gene expression in the protozoan pathogen T. vaginalis, are a group of divergent double-stranded (ds) RNA viruses. In the present study, the complete 4674-bp cDNA sequence of a 4.6-kb ds RNA from a newly identified TVV2–1 isolate was determined. The sequence of the plus-strand mRNA contains four open reading frames, which encode overlapping...
